Ee il; known that i, HERBERT e Citizen. oit thev United States, Leiter-Jood. State oi 7i-linten, residing; el; in the county oft Cnyeliogsi Unio, lieve invented e ee tain new and useiiil improvement in Closures for Containers, oi? which the following e iiill elem, end exact description? reference being; luid to the accompanying drawings.

This invention is e elosnre for containers glass and siiniler material., one' object 'tlie invention being to provide a closure liieli .mene Without a bend,.eixd Afippiied :ind sealed without. ai beading operation Another object of the invention to il vide i eiosnre with straight orA finit enacting :flange portions which. remain straight or dat et eil times; and another object is to provide. e closure of suoli eonstrueiion that it een be applied to and securely seal containers having :i considerable'variation in their externiil diameters; sind :i stiil :further object is to provide :i closure vwliiclo 'troni its nature Wiil prevent breakage ofthe oonteiiier during the sealing opere-tiem i.Seether objet-tof the invention is to pro vide :i closure which can be applied with equal facility end eli'eeiireness 'to it eonminer which ie iiiiring at tlie'iop like in ordinary tumbler, it being understood that tite tumbler containers in `use at the present time are iii-ede sti-:iight or of uniform diemeter et the sealing portion.

Tirilli ilnse ferions ,objects in, viewthe inventien consists in the feet-uros of condescribed end pointed ont in the Claims.

in tlie drawings lim-.tiling a part of 'this eitiontion, ,Fien-re l iS a. seetionfil View oi' the blank from which tlie'elosnre is nmde; Q is :i sectional View illustrating tine iirs step in the punching or shaping pretese; VFig: B i similar View showing e seeoml step mid Fig. 4l is a. vertical sectional View of the eiosnro eoinpleted and ready to receive the rubber gasket or 'peeking ring; `i `igljf t is w. sectional, View s'hmving' tile elo'- snre "willi the rubber gasket or packing ring arranged therein sind epplied to the top of i. eonini .er und lFig: 6 is :i .eetioinel View snowing' die (container with closure seeiefl thereon and for vtiring the eeelinig;

operation.

'my invention i. employ e disk l0, ol.3 tliin leeqnereo tin or similin' material, und this disk is iirstpunched or shaped to provide :i circuler zip or clos-nre with the nsnfii :innular eorrngetion or upset portion lll which ie adapted to receive the Lipper edge ot' the container. The ratp or closure is then slmped with it surrounding angled flange compris ing the ontwtnrdlgiT sind downwardly extendin@t portion 1 2, sind the in wirdly and down Werrlly extending portion l-i, the extreme edge being1 rolled inicia uponitseli' its shown it 13 providing e reinforcement i'or the inwardly and c ownwai'dljf inclined portion of tlie flange.

As tlins Constructed, the closure is [no `vided with an angled ianggje, the .lower er free portion of seid tiiinge being;` reiii'limfeed. i-i rubber gasket ox' elim/ie peeking ring l5 is fitted into lxe :ingle oi' the ilzinge and will remain thus seated ii'itliont danger of dis- Ilodginent. 'iiie outwardly extending nor- 'tion i2 and inumrdly' extending portion i4 :ire both striiigflit and lint :ind remain so :it :ill times und wlien it is desired to seal the closure upon n, Container, the seid elosiire placed upon t-lie top oi the container lo, :1nd this t-ontaiiner with the Closure thereon is placed within and between the sealing, dies l? :ind Q and it will be noted LU that the angle or incline 19 of the die lil is exactly the same ns 1the ongle or ineiineizion ofthe portion 12 out the angle or inelirie Q0 el. the die 1"( is somewhat sliarer than the enqle or ineline of the portion 3.1i so. that Wnon tlfie dief-J` :tre broughty to.L the portion lill the angled iengge is upwardly and inwardly7 find in so y ijlie rubber gasket or peel lng ring is qnoezed into tight Contact with the exterior ,ofA the Container 'thereby effecting e per'- i'eetly tight. seal. The lower or free portion ifi ot' the angled flange being reinforced or fof double thickness, can be turned in in the manner described and will remain in such position. in View of the feet that this free oortion oi' the 'flange lies a Considerable inwerd movement, it is obvious that Closure constructed in tliis manner will. re., Vlily :ieeonnnodate itsell3 lo oinsiderfible "variations of external diinneiers in containers sind iii ille reinforced portion of the Harige should ne forced into eoninziet with 'the conta' fr' tli'ere will lue e eertein 'yielding lee to fact that the upper p 1'tion of the Piange is ot' less thickness than the lower portion and breakage of the container during the sealing` operation is thereby prevented. i

Under ordinary circumstances, the position of the upper portion o the flange of the closure does not change, the lower portion only moving toward the upper portion, and at the same time contracting in diameter and squeezing the rubber gasket or packing ring` `forcibly into close contact with the exterior ot' the container.

By avoiding the use of beading,l tools or.

appliances for sealing the closure, the operation can be accomlilished much quicker and easier and with less damage to both closure and container.

liaving thus described my invention, what I claim is:-

l. In a closure for containers and the like` a cover portion, a depending; rim eX- tendinn' at substantially right angles to said cover portion, a ring sloping downwardly and outwardly `from said ring, another ring;` annnlarly disposed to the iirst mentioned ringand sloping downwardly and inwardly, [he free edge ot' said last mentioned ring beingY reinforced` and a gasket carried between said ring:v and adapted to be tightly compressed against the wall of a substal'itially incompressible container by decreasing the diameter of the free edge of the lower ring.

A closure comprising' a cover portion, a rim exteniiling at substantially right angles to the plane of said cover portion, an ontwardly extending rimer carried by said rim whereby an obtuse angle is foi-ined between said rim and said ring'I` and a Second ring extending from the first mentioned ring and at an acute, angle thereto, the metal oit' Said second ring being` 'folded upon itself to forni mea-fier a reinforced tree edge for said second ring, and a gasket carried between said rings and adapted to be compressed against the eide wall of a substantially incompressible nien'e 4a ber by decreasing the angle between said rings and decreasing the diameter oit the free edge of said second ring.

3. As an article of manufacture, a Sealed package comprisinga container, said' con- 5o tainer haring substantially incompressible. side walls adjacent the month thereof, and a, substantially flat, cover extending `over the mouth of said container, a skirt exteiidn ing' over said incompressible side walls, said i skirt comprising;` angularly disposed rings with the lree edge o't the nndermost ring` re intorced and the area inclosed between said rings and the side wall ot' said container being` in ci'oss-sect.ion substantially an eqni- 6U angular triangle, and a gasket Within said area and under compression.

'l-. As an article of manufacture, a sealed package. comprising` a container, said container haringl a substantialiy incompressible straight cylindrical side wall adjacent the mouth thereof, a cover member extendins` over the month of said container, a skirt e". tending downwardly over said Straight ey-I lindrical side wall` said 'skirty comprising angularly disposed rings meeting at their outer extremity to form an outwardly elttending tl-shaped bead whereby the area inclosed between said straight cylindrical H side wall and said rings is substantially an l equi-lateral triangle, and a gasketwitliin Said area and exerting substantially iinitorin pressure npon all sides of said area.

In testimony whereof, lf hereunto afin; my signatur-c.
